This is such an interesting thread, but where I think caution needs to be the watchword.
When one lives in a country where the State is benevolent, elected, and accountable to that electorate on a regular basis, then safeguards can be built in.
However, what if the State is not benevolent? Hitler and the Nazis were extremely efficient in how they dealt with people they considered had no right to live: not only Jews but gays,gypsies,and the mentally ill or those considered sub-normal. When life is not seen as a gift, then life can become cheap, and expendable, like so much in a consumerist society.
We must be careful what we wish for.
